This method is not only time-consuming but also difficult to achieve real-time monitoring, especially when stratified sampling is required.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a positionable water pollution detection device, including a spectrometer 1. A detection slot is located on the right rear end of the spectrometer 1, and a water pump 2 is located on the left rear end of the spectrometer 1. A connecting pipe 3 is connected to the right end of the water pump 2, and a sample box 4 is connected to the other end of the connecting pipe 3. The sample box 4 is snapped into the detection slot. A discharge pipe 5 is connected to the right rear end of the sample box 4, and a sampling tube 6 is connected to the left end of the water pump 2. A positioning float 7 is located outside the sampling tube 6, and the sampling tube 6 is inserted into the center of the positioning float 7. During water pollution detection, the sample box 4 is inserted into the detection slot. Insert the lower end of the sampling tube 6 into the water and let the positioning float 7 float on the water surface. The sampling tube 6 can be positioned at the depth of insertion into the water by the positioning float 7. Start the water suction pump 2. The water suction pump 2 draws water into the interior through the sampling tube 6 and introduces it into the sample box 4 through the connecting tube 3 until the sample box 4 sprays water out of the discharge tube 5 and stops the operation of the water suction pump 2. At this time, the sample box 4 is full of water. Since the sample box 4 is inserted into the detection slot, the detection slot can perform spectral detection on the water inside the sample box 4. Quantitative analysis of water quality is performed by utilizing the absorption, emission and scattering characteristics of substances on light, thereby detecting water pollution.

[0029] The sample box 4 has an opaque side located on the outer rear end of the spectrometer 1, while the other five sides are transparent. The spectrometer 1 utilizes the absorption, emission, or scattering of light of different wavelengths by substances in the water to form characteristic spectra, thereby detecting and analyzing substances in the water. The spectrometer 1 in this technical document can achieve its water quality detection function using existing water quality spectrometers. Water quality spectrometers are existing known and publicly disclosed technologies, and their specific structure and working principle are also existing known and publicly disclosed technologies, so they will not be described in detail here.

[0030] Preferably, a fixing clip 8 is connected to the center of the upper end of the positioning float 7, and the sampling tube 6 is snapped into the fixing clip 8. A positioning scale 9 is provided on the outer wall of the front end of the sampling tube 6. During the process of inserting the sampling tube 6 into the water, the sampling tube 6 can be fixed to the positioning float 7 by snapping into the fixing clip 8, and the insertion depth into the water can be adjusted by sliding up and down inside the positioning float 7 and the fixing clip 8. The length of the sampling tube 6 at the lower end of the positioning float 7 can be accurately displayed by the positioning scale 9 on the outer wall of the front end, thereby accurately displaying the insertion depth of the lower end of the sampling tube 6 into the water. This allows the water pollution detection device to accurately sample and detect different water layers through the cooperation of the sampling tube 6 and the positioning float 7 and the display of the positioning scale 9, thereby improving the detection accuracy.

[0031] Preferably, a power motor 10 is installed inside the left rear end of the spectrometer 1, and the power motor 10 is located at the rear end of the water pump 2. A motor shaft 11 is rotatably connected to the center of the rear end of the power motor 10, and the rear end of the motor shaft 11 extends into the water pump 2. Two limit frames 12 are connected to the left side inside the water pump 2. A steering shaft 13 is rotatably connected to the central axis of the two limit frames 12 and is limited by a limit ring. Multiple pump blades 14 are connected to the outside of the steering shaft 13, and the multiple pump blades 14 are located between the two limit frames 12. Helical teeth 15 are provided at the rear end of the motor shaft 11 and the right end of the steering shaft 13, and the two helical teeth 15 mesh with each other. During the process of water pump 2 sucking water, the power motor 10 is started, the power motor 10 drives the motor shaft 11 to rotate, and drives the steering shaft 13 to rotate through the two helical teeth 15. Then, the steering shaft 13 drives the multiple pump blades 14 to rotate inside the water pump 2, so that the left end of the water pump 2 generates suction, thereby sucking water into the interior.

[0032] Preferably, a sealing ring 16 is provided inside the front end of the discharge pipe 5, and a sealing plate 17 is provided at the rear end of the sealing ring 16. A sealing head 18 is connected to the center of the rear end of the sealing plate 17. The sealing head 18 is inserted into the rear end of the sealing ring 16. A sealing connecting rod 19 is connected to the center of the rear end of the sealing head 18, and the sealing connecting rod 19 passes through the central axis of the sealing ring 16 and extends to the outside of the front end of the sealing ring 16. A spring seat 20 is connected to the rear end of the sealing connecting rod 19. The spring seat 20 is slidably connected inside the discharge pipe 5. A sealing spring 21 is provided between the sealing ring 16 and the spring seat 20, and the sealing spring 21 is located outside the sealing connecting rod 19. During the process of the water pump 2 introducing water into the sample box 4, the gas inside the sample box 4 is discharged outward from the discharge pipe 5 under the pressure of the water. The gas inside the sample box 4 is squeezed into the discharge pipe 5 and overcomes the blockage. The elastic force of spring 21 pushes the sealing head 18 backward from inside the sealing ring 16, allowing the discharge pipe 5 to connect with the outside, thereby expelling the air inside the sample box 4. When the air inside the sample box 4 is completely expelled, the water introduced into the sample box 4 will spray out from the discharge pipe 5. When the discharge pipe 5 starts spraying water, it indicates that the sample box 4 is full of water. At this time, the operation of the power motor 10 is stopped, so that the water pump 2 no longer introduces water into the sample box 4, causing the water pressure inside the sample box 4 to decrease. The water pressure inside the sample box 4 cannot overcome the elastic force of the sealing spring 21, causing the sealing head 18 to be locked back into the sealing ring 16 under the action of the sealing spring 21 and the drive of the sealing connecting rod 19 and the spring seat 20, sealing the rear end of the discharge pipe 5 to prevent the water inside the sample box 4 from flowing out, ensuring that the sample box 4 is full of water and ensuring accurate detection.

[0033] In addition, after the test is completed, the sampling tube 6 is removed from the water and the water pump 2 is turned on again. The water pump 2 draws air into the interior and introduces the air into the sample box 4. The sample box 4 uses the introduced air to squeeze the water inside out from the rear end of the discharge tube 5. When the water stops spraying from the rear end of the discharge tube 5, the water inside the sample box 4 is drained and the operation of the water pump 2 is stopped.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
